SPECIFICATION tornng part of Letters Patent No. 288,260, dated November 13, 1883. Y

' Application iiled April 7, 1883. (No model.)

To @ZZ whom it may concern:

Be it known that I, 'WILLIAM SPRAGUE PosT, a citizen of the'United States, residing at Boston, in the county-of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Refrigerating Structuresbe aiulhelear, and exact description of the invention, such as will enable others skilled in 1o the art to which itv appertains to make and luse the same, reference lbeing had to the accompanying drawings, and to letters or iigures of reference marked thereon, which form a part of this specication.

This invention relates to refrigeratin g structures, but more especially to oars for transporting perishable matter-as fish, meat, vegetables, andthe like-and maintain continually therein a cool dry atmosphere. The especial 2o object is to obtain a more even temperature than is usually eftected by having the refrigerating struct-ure at either or both ends, but likewise economy in space. Inthe latter case the circulation is from the center to the ends,

whilein astructure provided with an overhead cooling apparatusconstructed in accordance with this specification the circulation is at right angles to its length. n'

The general features of my invention consist in an ice tank or tanks extending the entire length of a rooin 'or cellar, or, in the case of a refrigerating-ear,in .the roof portion,to be of monitor pattern. This tank is to be divided into a series of tanks, and arranged with a.

35. drip-pan, air-eonduits,and further provided with outlet-pipes, to enable the condensed moisture and pickle solution to readily pass oft'. Minor details and the relative position of the various parts vone with the other will be 4o more fully de'smfibed` hereinafter.

The drawings accompanying this specication represent in Figure `1 a cross-section through a car containing my invention, while Fig. 2 represents a longitudinal section taken `4.5 on the line a' c of Fig. l, and looking in the direction shown by arrow 1.

Invthe `drawings, represents a' refrigeratar-oar, of which c c are the sides, and b the door, the saine being provided with some non-v 5o conduting material within their walls. The

and I do hereby declare' the following to,

` c, which extends a `against the top and side portions of the monitor roof; but to allow passage of air round upper or monitor-roof portion, B, contains all t-he necessary apparatus for cooling the air and maintaining a continuous current throughout the Vcar, and consists of two tanks or icev chambers, C C, whose general shape is rectangular, and in practice are to be subdivided into a series oi' smaller tanks, c c, which are provided with openings or hatchways d d, for relling with refrigerating material.

The entire structure rests on cross-beams D D, Src., extending across the car A. Lengthwise of the car IproVideaniid-rib or partition, short distance below the beams D' D, Sto., while between this partition e and the interior wall of the tanks c c,I erect secondaryT partitions or divisions E E, which extend downward, resting on theY aforementioned cross-beams. iTo these partitions I secure the drip-pans F F.

As the several portions of the car are alike on either side of the center, I shall proceed to further describe but one-bali` only of my apy paratus.

The secondary wall E does not reach quite to the roof of the oar, thereby allowing oi' dow of air through the passage f upward, and then down around the cooling-tank C, which may be composed oi' the individual tanks c c.

The icetank or tanks c c are set snugly the upper side of said tanks I form the top Vand outer side of the tanks of corrugated iron, and these corrugations run at right angles to the length oi' the car. (See Fig. 2.) The crest portions g g bear against the roof, and the hollow parts h h are thereby separated one from the other, and forni a series of conduits or air-passages, .and permit the air to pass round through them, as shown by the dotted lines and arrows in Fig. 1.

Thel drip -pan F, as I have previously stated, is secured at one end to the lower portion of the secondary partition E, and may be continuous the entire length of the reirigerating structure, and rests on blocks, which in their turn are supported 'upon the beams D. This pan is to have a slight inclination, as shown, andterminates in a gutter or conductor, G, with an outer raised lip, to admit of passage 10o of waterl along it, and'still prevent its escape side,

the beams D I), and has a slight pitch from either end toward the center of the car, where it unites with a vertical pipe, m, leading downward out of the car.

To complete and form a perfect circulation with the apparatusabove described, I have attached to the inner wall of the car, with a proper and suitable space, 7c, intervening, the partition Z. This likewise extends the entire length of the car, but does not quite reach the floor b. This air-space' k is subdivided into divisions corresponding to each ice-reservoir c above.

To adapt my refrigerating structure to partition or compartment cars' in which it may be desirable to cool one, two, or more compartments, as the case may be, or where there issufcient perishable material to iill but one compartment, I provide each tank or reservoir c and its surrounding air-channels withv a damper or dampers, 'i i. Suppose compartments cooled by the tanks l and 3 (see Fig.

2) are to be used, dampers i fr' on 2 and the remaining tanks are to be closed, and the circulation is consequently maintained only over the tanks which correspond to the co1npartments of the car in use-viz., l and3.

Having thus described the various parts relatively to each other, I will now proceed to follow out and describe the circulation.

After the ice-reservoirs are filled and the car closed to external atmosphere, the air surrounding the ice-chamber naturally becomes chilled from contact therewith, and passes down the space or spaces 7c on either side of the car, as shown by the arrows.

air, rising to take its place, strikes against the mid-rib e and passes up to the top of the secondary partition E, where said current is subdivided, a portion passing lalong over the top of the tank c by and through the air-passages h h, duc., formed by the 'corrugated top and Warmer the remainder passing downward, and thence between the bottom of said tank and the drip-pan F, being cooled in its passage, andvnally the two portions reunite just beyond the conductor G. This completes the circuit, and it is very evident that the air can be kept at a more even temperature by the vcurrents so produced, and which effect a circulation at right angles to the length of the car. A further advantage is economy in space in the carrying capacity of the car above those in which the refrigerating apparatus is located in one or both ends. The waste-pipe H is suspended just below I claimy l. In a refrigerating structure, the ice-reservoir arranged at the top and fitting snugly thereto, with a portion of its periphery and top corrugated to provide air-passages over and around it, substantially as stated.

2. A refrigerator-car having ice-chambers C C immediately under its roof, in combination with passages between said chambers for the ascent of air, and passages extending around and down from the sides of said chambers for the descent of air, substantially as set forth.

3. The icecha1nbers C' C at the top of a refri gerator structure, in combination with midrib e, extending down from the roof, and auxiliary partitions E, which are arranged on each side of said mid-rib, and do not extend quite to the roof, spaces being left between said midrib and partitions for the descent of air, substantially as set forth.

4. In combination, the tank c, for containing refrigerating material, and provided with corrugati ons g g h h, the drip-pan F, conductor G, and waste-pipes H, j, and m, substantially as stated.

Y 5. In refrigerating structures, the corrugatedv tank c, in combination with mid-rib e,r partitions E and Z, and drip-pan F, constituting.

air passages or conduits for proper cooling and circulation of air, substantially as described.

6. In refrigerating structures, the ice-reservoirs C C, arranged in the roof of said structure, and provided with a main air-passage, the latter subdivided by mid-,rib e, substantially as stated.

In testimony whereof I affix my signature in presence of two witnesses.
